Two trains start from the same place and move in opposite directions. One moves 33mph and the othermoves at 27mph. How long does
it take for them to be 480 miles apart
1 answer:
Answer:
8 hours
Step-by-step explanation:
Train A moves at speed v1=33mph
Train B moves at speed v2=27mph.
Let t be the time when they are 480mi apart.
d1=v1×t distance traveled by train A
d2=v2×t distance traveled by train B
d1+d2=480mi
v1×t+v2×t=480mi
(v1+v2)×t=480mi
(33+27)×t=480mi
60×t=480mi
t=480/60=48/6=8hours
